You are given the sample mean and the population standard deviation. Use this information to construct the​ 90% and​ 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. If​ convenient, use technology to construct the confidence intervals.   A random sample of 45home theater systems has a mean price of ​$124.00. Assume the population standard deviation is ​$16.30.   Construct a​ 90% confidence interval for the population mean.   The​ 90% confidence interval is ?    95% confidence interval for populatiion mean?  95% confidence  interval is wider than 90%
